Common Errors in the Use of Prepositions
Knowing how to use prepositions correctly shows your mastery of the language.
This post is about the common errors in the use of prepositions.
Since and For
Since means ?from a point of time in the past'. It should be used with the present
perfect tense.
He has been ill since last week. (He fell ill two weeks ago and has been ill ever
since. He is still ill.)
It has been raining continuously since yesterday morning. (It is still raining.)
Don't use the simple present or present continuous tense with since. It is wrong to
say ?He is ill since last week' or ?It is raining since yesterday morning'.
For is used to refer to a period of time. It shows duration.
He has been ill for two weeks.
It has been raining for two days.
She has been sleeping for 10 hours.
Many ESL students commit the mistake of using since when referring to a period of
time.
He has been working for two hours. OR He has been working since 11 am. (NOT
He has been working since two hours.)
We have been living here for ten years. OR we have been living here since 1999.
(NOT We have been living here since ten years.)
Beside and Besides
ESL students often get confused about the meaning and use of these two words.
Note that beside means ?by the side of' and besides means ?in addition to'.
